CATTLE-GUARD FOR RAILWAYS.

Specification of Letters Patent.

Application filed April 8, 1911. Serial No. 619,815.

To all whom it may concern:

Be it known that I, JOHN W. COMER, a citizen of the United States,residing at Ulm, in the county of Cascade and State of Montana, haveinvented certain new and useful Improvements in Cattle-Guards forRailways, of which the following is a specification, reference being hadtherein to the accompanying drawing.

This invention relates to cattle guards for preventing cattle and otherlive stock from crossing railroad tracks from one field to another.

The invention has special reference to cattle guards of this kind whichare so constructed and arranged that when the cattle attempt to stepupon the same it will yield and thereby cause the cattle to retreat.

The invention has for its object to pro vide an improved cattle guard ofthis kind which will be simple in construction and effective inoperation, and may be readily repaired.

Referring to the accompanying drawings: Figure 1 is a plan view of asection of a railway track provided with a cattle guard constructed inaccordance with this invention. Fig. 2 is an enlarged detail view of oneof the members of the sub-structure of the cattle guard, in verticalsection. Fig. 3 is an enlarged detail View of another member of thesub-structure of the cattle guard. Fig. 4 is a plan view of the deviceshown in Fig. 1 with the top of the cattle guard removed. Fig. 5 is anenlarged detail View in perspective of one of the brace members of thetop of the cattle guard. Fig. 6 is an end view in cross section of thedevice shown in Fig. 1. Fig. 7 is a side view in longitudinal section ofthe device shown in Fig. 1. Fig. 8 is a detail view in perspective ofone of the top plates of the cattle guard. Fig. 9 is a detail view inperspective of a washer serving as a nut lock in the cattle guard. Fig.10 is an enlarged detail view of the underside of a portion of one ofthe top plates of the cattle guard and one of the .brace bars showingthe means for locking the brace bar thereto. Fig. 11 is a detail view inlongitudinal section of a portion of the device shown in Fig. 10. Fig.12 is a detail section of the lower end of the socket member which isadapted to support the tread supporting rods showing the drain apertureformed in the bottom of said socket member.

In the accompanying drawings a portion of the rails 1 resting on ties 2of a railway track are shown together with longitudinal beams or strips3 secured to the outer ends of the ties 2. Located between the rails 1is asheet metal plate4and between each rail 1 and the outer longitudinalbeam 3 is a sheet metal plate 5. The plates 4 and 5 are preferablyformed of sheet steel and the plate 4 is preferably formed of twosections 6 secured together at their abutting edges by metallic straps 7riveted thereto. The outer edge of each side of the plate 4 is formedwith a depending portion 8 from the lower end of which projects alateral flange 9, the edge of which is located beneath the head of arail 1. The inner side of each of the plates 5 is formed with adepending portion 10 having at its lower end a lateral flange 11 whichprojects beneath the head of the adjacent rail 1. The opposite edge ofeach plate 5 is located adjacent to the longitudinal beam 3. The plates4 and 5 are supported on pairs of vertical rods 12 located at each endof said plates each of said rods 12 being hinged at its upper end to apair of ears 13 depending from a brace bar 14 extending across the underside of the plates 4 and 5 adjacent to each end thereof. The other endof each of the rods 12 is hinged to a bolt 15 at the bottom of aV-shaped metallic socket member 16 provided with lateral flanges 17which are secured to cross ties 2. Located beneath the middle portion ofthe plate 4 are pairs of transverse plates 18 secured at their ends tocross ties 2 and secured to each of said transverse plates 18 are pairsof carriage springs 19 each secured at one end to the opposite ends ofthe plate 18, the other end of each of the carriage springs 19 beingprovided with a friction roller 20 which bears against the underside ofthe plate 4. The plates 5 each have a pair of carriage springs 19mounted beneath the middle portion of said plates similarly to thesprings employed in connection with the plate 4. Hinged to each end ofthe plates 4 and 5 is a transverse plate 21 which is inclined downwardand loosely rests upon metallic strips 22 secured to a pair of crossties 2.

The brace bars 14 are preferably secured to the plate 4 by means ofbolts 23 and nuts 24, said nuts being held in position by means of apiece of sheet metal formed with a short narrow strip 25, and a circularWasher head to step upon the plates 26 having a bolt hole 27, the strip25 having a lateral bent end portion 28. This device is placed againstthe brace bar 14; on the bolt 23 and after the nut 24 has been screwedup on the bolt the portion 29 of the washer 26 is bent over the side ofthe nut and with the bent portion 28 overlapping the edge of the bracebar 14 serves as a nut lock.

By means of the foregoing construction a cattle guard is provided whichwill prevent the cattle and other live stock from crossing the railwaytrack, since when they attempt t and 5, the latter will yield to theweight of the animals, thereby stopping them and causing them toretreat. It will be seen that the pressure by reason of an animalstepping upon the plates 4 and 5 will cause said plates to yield whenpressing the springs 19, thereby causing the plates 4: and 5 wheneverpressure is brought to bear upon them to move longitudinally anddownwardly in either direction, according as the pressure is producedthereon. The socket member is provided with a drain aperture 16 formedin the bottom thereof.

What I claim is 2- 1. In a cattle guard of the character described, asheet metal plate located adjacent to a railroad track and having pairsof vibratory supports, and sets of springs normally holding said platein elevated position and permitting said plate to have a longitudinaland downward movement.

:2. In a cattle guard of the character described, a railway track, asheet metal plate located between the rails of said track, pairs ofvibratory supports beneath said sheet metal plate, and pairs of springslocated beneath and having a sliding bearing against said sheet metalplate.

3. In a cattle guard of the character described, a railway track, asheet metal plate located between the rails of said track and having alateral flange at each side projecting beneath the head of the adjacentrail, pairs of vibratory rods secured to the underside of said plateadjacent to each end therei of, and pairs of sprlngs located beneath themiddle portion of said plate.

4. In a cattle guard of the character described, a railway track, asheet metal plate located between the rails of said track, vi-

. bratory supports secured to the underside of said plate, springssecured to the underside of said plate, and a hinged inclined plateloosely mounted at each end of said plate.
